Specification of Letters Patent.

Patented Mar. i4, iigi.

' Oak Park, in the county of Cook and Sctate have invented certainnewand Tires for Wheels, and

of Illinois, useful Improvements in of which the following is a full,clear, exact specification. j

My invention relates to tires for wheels, and more particularly to thatclass in which the tires are composed of replaceable sections, andcomprises an improved means for securing the sections in easilydetachable engagement upon the wheel, in entirely independent relationso that one section may be replaced without in any way affecting theremainder of the wheel.

Referring to the drawings forming a part of this application in whichthe several reference numerals indicate similar parts throughout, Figure1 is a side elevation of a portion of a wheel containing my improvementsshown partly in section. Fig. 2 is a sectional view on the line 2-2 ofFig. 1. Fig. 3 is a portion of one side of the tire securing means inperspective and Fig. 4 isa portion of the opposite tire securing meansinv perspective.

My improved means for securing the sections of the tire in place is notlimited to any particular kind of sections.. It is however, especiallyadapted for a wheel formed of pneumatic sections, for the reason thatthe means devised separate each section by one of a series of endsupports so thatthey are in no way dependent upon one another. l

This enables the replacement of one section for another without in anyway interfering with the other sections forming the tire. The sectionsillustrated in the present embodiment comprise the outer inflatablecovering 1 of rubber or other' suitable material, and the inner tube orlinin 2 likewise of rubber or other suitable material and provided witha nipple 3 of any usual construction projecting through the rim 4 of thewheel and through the intermediate members as will later be described.The sections are provided on either side'with means for attaching themto the rim, as for instance the flanges or beads 5. These engage withicorrespondingly formed members, as the flange 6 on the one side, andthe sectional ianges 7 on the other side. The ange 6 preferably extendsentirely around the wheel and is formed on the circular band 8 fitted tothe periphery of the wheel and hav-ing an inclined outer surface 9. Eachiange 7 embraces a section of the tire and is formed upon a band section10 having its inner surface inclined to correspond with the inclinedsurface 9. The outer surface of these sections are preferablyperpendicular to the vertical in transverse cross section to afford asuitable seat for the respective sections of the tire. Supports 11 areformed on the band 8 to support the ends of the tire sections and tofurthermore separate the sec- .tions so that they will be entirelyindependent of each other. A preferred form of support comprises thehollow metal block 12 in which is secured the block 13 of suitablematerial, such as rubber.4

The continuous band'8 is provided with dove-tailed plates 14, and theband sections are likewise formed'with dove-tailed grooves 15 forengaging the dove-tailed plates. Each section is here' shown as havingtwo such joints, but more may be used if desired. With such a securingof the band sections with the continuous band, it is not necessary thatthe two inclined surfaces be finished, it only being necessary that thefinishing be done upon the dove-tailed joints themselves. The membersare secured together preferably by bolts 16 passed through holes formedthrough the dove-tailed joints. Suitable perforations 16 and 17 areformed in the band 8 and band sections l0 for the admission of thenipple of the tire section..

All that is necessary when replacing a tire 'section is to remove thetire securing bolts and slide the band section outwardly su'icientlyalong its dove-tailed connections, to clear one side of the tire sectionfrom its engaging member. This permits the tire section to be withdrawnand another one put in its place. The end supports together with thedove-tailed connections and securing bolts make a strong construction,yet one from which the tire sections are easily removed.

Having thus described my invention, I claim- Y 1.` A wheel rimcomprising a metal band forming a`continuous section having an inclinedouter face extending substantially across the entire width of the wheelrim, a band section having an outer tire engaging portion and having abeveled inner portion adapted to engage and seat upon the inclined faceof the band, a transverse rib on one of said sections adapted tointerlockwith a registering groove in the other section to preventlongitudinal movement of said sections with respect to each other, saidrib having a fastening means extending therethrough to secure thesections in position.

2. A wheel rim comprising a metal band forming a continuous sectionhaving an inclined outer face extending substantially across the entireWidth of the Wheel rim, a band section having an outer tire engagingportion and having a beveled innerv portion adapted to engage and seat.upon the inclined face of the band, a transverse rib on one of saidsections adapted to interlock with a registering groove in the othersection to prevent longitudinal movement of said sections `with respectto each other, each of said sections having a transverse opening adaptedto register with each other, and

securing means passing through said openings entirely through the Wheelrim.

3. A wheel rim comprising two superimposed sections, each having meansfor engaging one side of a tire section, the con` -tactlng surfaces ofsaid sectlons belng 1n# and band section and fastening means extendingthrough said band and band section transversely of the tire for holdingsaid band section removably in place.
